EEG 101: An Introduction to the Essentials
Electroencephalography (EEG), is the technology for recording the electricity generated by the brain from the scalp surface. Applied first to humans in the 1920s by German neurologist Hans Berger, the electroencephalogram records the net sum of all electric fields generated by the brain from electrodes attached to the scalp.

What Is EMG (Electromyography) and How Does It Work?
EMG (electromyography) records the movement of our muscles. It is based on the simple fact that whenever a muscle contracts, a burst of electric activity is generated which propagates through adjacent tissue and bone and can be recorded from neighboring skin areas.

What is GSR (galvanic skin response) and how does it work?
The galvanic skin response (GSR, which falls under the umbrella term of electrodermal activity, or EDA) refers to changes in sweat gland activity that are reflective of the intensity of our emotional state, otherwise known as emotional arousal.

5 Essentials for an Optimal EEG Equipment Setup
While EEG is not a brain imaging method with the same high spatial resolution as MRI, the temporal resolution is effectively unparalleled. Combine all of this with its relative portability to MRI, PET, etc., and it’s clear why EEG is one of the main methods used in neuroscience and other fields today.
